Germany has something like this as well (it's called BAFOEG). It's not for tution (because there isn't any) but for your cost of living during study. It carries zero interest, you only have to pay back half of it and the pay back is capped to 10k total.

It should be mentioned that a) your parent's income (or yours if you are over 25) needs to be low enough for you to qualify b) it requires you to finish within the expected timeframe (possibly also have certain grades? Not sure about that as I didn't qualify) and c) it's not just for university but also for vocational training.
